柴达木盆了立体地质与油气预测

笔者在柴达木盆地进行3次野外地质调查，收集并参考了大量资料，编绘了柴达木盆地地质图、纵横剖面图、构造等高线图、等厚度图和不同深度地质图，借以研究盆地地下地层、构造、湖盆演化历史，并对古生代海相油源和含油区、中侏罗世油源和中新生代含油气区及油气田进行预测。

Stereo-Geology and Oil-Gas Prediction of the Qaidam Basin

Stereo-geology of the Qaidam basin and their characteristics; It is mainly re-flected through the contour maps, isopch maps, profiles and geological maps of various depths of the basins structures, their characteristics map be summerized asfollows: 1. The inheritance and disagreements of the structures. In general, there is a good in-heritance between the basement structures and the cover structures, there exist a pre-Mesozoic reversed S-shaped system in the basment and a Meso-Cenozoic reversed S-shaped system in the cover. The two system are roughly inheritance. 2. The history of developmenf and evloution of the basin, from NW to SE, the struc-tures and deposits of the basin show the features of overloppig in the east and offlaping in the west. The evolution of the lake basin can be divided into three-stages, and have record-ed the development regularitites of structures, deposits and oil-gas. Hydrocarbon sources and oil-gas prediction: 1. The paleozoic sources and their prediction, there are the possibility of finding Pale-ozoic marine hydrocarbon sources in the basement of the Delingha depression and the base-ment of the southwestern basin. 2. The Mesozoic sources and prediction of the Meso-Cenozoic petroleum provinces. With the Huangshi-Niubizilinang fulated rise belt as the boundary, the authors have divided the wide area north of Nan Us-Yiliping-Nanbazian into the western and the northeastern prospective petroleum areas.
